MECHANISM.

SPECIFICATION forming part of Letters Patent No. 650,427, dated May 29,1900.

Application filed January 11, 1900. Serial No. 1,133. (No model.)

To aZZ whom it may concern.-

Be it known that I, MAX SIELAFF, a subject of the King of Prussia,German Emperor, and a resident of 23 Spenerstrasse, Berlin, in theKingdom of Prussia, German Empire, have invented certain new and usefulImprovements in Coin-Freed Mechanisms, (for which application for patenthas been made in Germany, No. 16,492, on the 3d of March, 1899, and inFrance, No. 283,349, on the 12th of December, 1899,) of which thefollowing is an exact specification.

The present invention relates to improvements in coin-freed mechanisms,and has for its object to provide means for opening the receiver whenthe mechanisms are not in position for use, so that in consequence allcoins inserted are conducted to the outside again.

lVith coin-freed mechanisms hitherto employed the driving mechanismoftenwas injured by coins inserted into the apparatus while theparticular parts were not in the right position for taking up the coinsor were not in the position to be coupled by the coins.

By the mechanism forming the subject-matter of the present applicationcoins are prevented from being inserted into the apparatus when thedifferent parts are not in right position. The particular constructionfor attaining this end consists of a coin-receiver having two partselastically connected together, one of which by means of a crank-levercan be removed from the other, whereby this crank-lever at its freeextremity is of a form that not only the rotating slide usually employedbut also the driving mechanism can effect its displacement as soon asthe latter leaves the position for taking up the coins.

My invention will be better understood with reference to theaccompanying drawings, in which- Figures 1 and 2 represent lateral viewsof my apparatus, and Fig. 3 is a plan View of the rotatable slide andshowing a sectional view of the end of the lever m. Fig. 3 is ahorizontal sectional View of the driving-disk and 1ever m and showing inplan the rotatable slide in connection with these parts. Fig. 4 is aplan View similar to Fig. 3, showing a slightlydifierent construction ofslide. Fig. 5 is a View similar to Fig. 3, showing the drivingdisk herehaving angular recesses instead-of rounded ones.

In the drawings a coin-freed mechanism for distributing liquids isrepresentedas an example. The apparatus essentially consists of a cooka, the plug of which is moved by the rotating driving-disk b. Themovement is imparted to the disk I) in known manner from the exterior bymeans of a slide a, coupled with the disk h during a part of therotating movement when a coin has fallen into one of the slots cl of thedisk I). The slide 0 has a portion of its perimeter removed, as shown at00, whereby the slide will be permitted to be rotated to an extentequivalent to the length of the cut-away portion. In its rotation whenthe parts are in the position seen in Fig. 3 the points 00 00 wouldstrike against the projection 0 of lever m, presently described, andthus the rotation of the slide a would be limited in each direction. Theslide 0 has sector-shaped portions y formed by cutting away the slide,as at z 2 Above the driving-disk b is arranged in suitable manner acoin-receiver consisting of two parts f and g. Both parts f g areconnected together by a joint h. The part fis fixed, while the secondpart g can be turned. In normal position both parts are kept close toeach other by means of a spiral spring '5. Underneath the coin receiverthere is arranged a funnel discharging all coins falling out of thecoin-receiver. When the coin regularly has passed the receiver, itenters a coin-channel Z and is conducted to the driving-disk b. A doublelever m is rotatably fixed to the casing e at n. The form of thiscrank-lever m clearly can be seen from Figs. 1 and 2. The upper partabuts against the movable part 9 of the receiver. The lower extremity isprovided with two projections o 0 the lower one of which extends intothe path of the circularslide 0, while the upper projection 0 abutsagainst the disk b, as can be seen from Fig. 3. The periphery of thedisk is provided with a number of depressions 10, corresponding to thenumber of the slots. The position of the parts is arranged in such amanner that the lever m or, more precisely, its projection 0' onlyextends into one of the recesses 19 of the driving-disk, when the latter is in position to take up a coin. Fig. 3 shows the parts in positionready for receiving a coin, and if the coin is dropped into the receiverit will fall down into a slot (1 of disk b, at which time the sector yof slide 0 is below the said slot 01; but by rotating the slide c-say inthe direction of the arrow in Fig. 3the sector 11 will first clear thecoin resting in slot d, which coin will then drop down partly into space22 of slide 0, and as the slide 0 is continued to be turned the othersector 1 will strike the coin, and thus cause the disk I) to be carriedaround with it in its further rotation, and thus turning the plug ofcook a, the coin thus constituting the looking medium between the diskI) and slide 0. As soon as the disk is removed from the position forreceiving a coin the projection 0 of the lever m advances and lies uponthe cylindrical part of the disk, whereby the lever is displaced, thecoin-receiver opened, and no coins are allowed to enter the coin-channelZ,and consequently to enter the apparatus.

My improved arrangement is of great advantage for coin-freed mechanismsselling liquids for the reason that the liquid trickles down when thecock only is opened a little without it being possible for the wholemovement to be effected. Furthermore, in this position no further coinscould be inserted, and the apparatus cannot be used before thedriving-disk is adjusted in position. When new such an apparatus doesnot work exactly, my improved arrangement prevents with certainty theinsertion of coins, so that no buyer can be robbed of his coin. Allcoins being inserted when the apparatus is in inexact position arecarried to the outside through the funnel k.

In Figs. 4 and 5 I show the slide 0 as being provided with a slightrounded or angular depression p to enable the operator to close thecoin-receiver even when the rotating slide is not in its startingposition.

Having thus fully described the nature of my said invention, what Idesire to secure by Letters Patent of the United States is 1. Incoin-freed mechanism, the combination with a coin-receiver adapted to beopened for discharging coins, of a crank-lever m, a slide adapted to berotated from the outside for actuating the apparatus, a rotatable disk27 for taking up the coins, said slide and disk being adapted, when notin position ready for use, to act upon the crank-lever and cause thelatter to open the coinreceiver, all as specified.

2. Incoin-freed mechanism, the combination with a coin-receiver adaptedto be opened for discharging coins, of a crank-lever m, a slide adaptedto be rotated from the outside for actuating the apparatus and being provided with a peripheral depression, a rotatable disk I) for taking upthe coins, said slide and disk being adapted, when not in position readyfor use, to act upon the crank-lever and cause the latter to open thecoin=receiver, all as specified.

In witnesswhereof I have hereunto set my hand in presence of twowitnesses.
